Oxidative Stress, Endogenous Antioxidant and Ischemia-modified Albumin in Normolipidemic Acute Myocardial Infarction Patients

چکیده
Dyslipidemia appears to be a conventional risk factor for acute myocardial infarction (AMI). Several studies have reported decreased levels of antioxidants and increased levels of ischemia-modified albumin (IscMA) and lipid peroxides in dyslipidemic myocardial infarct patients. However, literature search reveals no reports of normolipidemic AMI patients with reference to antioxidants and IscMA studies. Therefore, this study determined the endogenous levels of antioxidants and IscMA in normolipidemic AMI patients so that prospective measures could be taken to avoid acute coronary complications. The serum lipid profile, albumin, uric acid, total bilirubin, malondialdehyde, conjugated dienes and IscMA levels were determined in 165 normolipidemic AMI patients and 165 age/sex-matched controls. In addition, serum lipid concentrations were estimated by enzymatic methods. Endogenous antioxidants were significantly decreased in AMI patients compared with controls. In parallel with this, serum malondialdehyde (MDA) and conjugated dienes were significantly increased in AMI patients compared with controls. IscMA levels were significantly increased in AMI patients compared with controls. As for the serum lipid profile, total cholesterol (TC), cholesterol in low density lipoprotein (LDL) and triglycerides (TG) were higher in AMI subjects. High-density lipoprotein (HDL)-to-cholesterol and LDL-cholesterol-to-HDLcholesterol ratios were also greater in AMI subjects.

Investigation of ischemia modified albumin, oxidant and antioxidant markers in acute myocardial infarction
INTRODUCTION Acute myocardial infarction (AMI) is still one of the most common causes of death worldwide. In recent years, for diagnosis of myocardial ischemia, a new parameter, called ischemia modified albumin (IMA), which is thought to be more advantageous than common methods, has been researched. AIM In this study, systematic analysis of parameters considered to be related to myocardial is...

Background: Myocardial Infarction (MI) is a leading cause of death in India. Whether dietary vitamins could reduce risk of cardiovascular disease among Indians is still not clear and very few studies have addressed the association between dietary vitamin acting as an antioxidant or pro-oxidant and its effect on risk reduction or aggravation in normolipidemic AMI patients. Objective: The goal of...
متن کاملGlycation abolishes the cardioprotective effects of albumin during ex vivo ischemia‐reperfusion
Hyperglycemia-induced oxidative stress plays a key role in the onset/progression of cardiovascular diseases. For example, it can trigger formation of advanced glycation end (AGE) products with ischemia-reperfusion performed under hyperglycemic conditions. For this study, we hypothesized that albumin modified by glycation loses its unique cardioprotective properties in the setting of ischemia-re...

متن کاملThe rehabilitation training and antioxidant status in patients with myocardial infarction
Introduction: Myocardial infarction (MI) is associated with increased oxidative stress and reduced antioxidants. Some studies have shown that exercise training increases the serum level antioxidants. Therefore, this study investigated the effect of rehabilitation training on antioxidant status in patients with myocardial infarction. Materials and methods: In this study, 20 patients with my...
